Paper Abstract

A mathematical model for the production of singlet delta oxygen, O2(1(Delta) ) from the reaction of a gas containing chlorine (Cl2) with the hydroperoxy ion (HO2+) in liquid basic hydrogen peroxide (BHP) is reviewed. A solution for the generator's Cl2 utilization, O2(1(Delta) ) yield and efficiency is obtained, which is applicable for both long and short gas exposure times over a wide range of Cl2 pressures and HO2+ molarities. It is shown that generator performance is characterized by six parameters. The dependence of these parameters upon generator geometry, Cl2 pressure, diluent ratio, HO2+ molarity, the gas and liquid flow velocities, and the gas and material properties is discussed. The yield is similar in form to the well-known transport solution for the fraction of O2(1(Delta) ) exiting a duct except that an effective gas residence time replaces the gas transit time. When the surface concentration of HO2+ is constant, i.e., in the well-stirred limit, this solution reduces to that obtained previously and, in this case, generator performance can be characterized by a set of universal performance curves dependent upon only three parameters. The model is used to examine the behavior of a rotating disk O2(1(Delta) ) generator at high pressure and Cl2 flow rates.
